Here is a post from several years ago tracking the process of making a bow. In this case, from Osage orange.
Not visible here are short hickory wedges that are jammed into the growing crack to keep the stave from snapping shut.
Not so with Osage Orange. The white new wood is visible in the stave above as the outer rings are worked down to a single thick growth ring.
This process is easiest with a sharp draw knife working downward. Your weight can be used to pull through the bark.
The growth rings are visible in the low raking light. The smooth area nearest the viewer is down to the desired ring. This will be the “back” of the bow meaning the side facing away from the shooter. Crossing the rings could cause the limb to “lift” and crack as the rings are stressed.
More to come.
